1'7 Claims.

This invention relates to machines for operating upon soles of shoes and is illustrated as embodied in a machine for simultaneously reducing the heel-seat portions of soles to form heel-seat tabs, and molding heel-breast covering flaps which have been split from said soles.

In United States Letters Pattent No. 2,125,328, granted August 2, 1938, on an application filed in my name, there is described a method of shoemaking which comprises splitting the heel end of an unattached sole to form a heel-breast covering flap and simultaneously therewith removing a layer of sole material to form a heelbreast receiving shoulder at the base of said flap, and thereafter reducing the heel-seat portion of the split sole to form a heel-seat tab preparatory to positioning the sole upon and attaching the same to the shoe. The sole may vantageously besplit and the heelbreast reng shoulder formed by the use of a manie disclosed in United States LettersPatent 9. 2,173,822, granted September 26, 1939, on 1 application filed in my name.

finished shoe shall approximately fill the attaching face or cup of the Louis heel of said shoe, iereby serving as a solid base to which said heel :iy be attached. The tab, however, should terminate well within the rim of the attaching face of the heel and should not be so thick that it prevents said rim from being forced into snug engagement with the overlasted counter portion of the shoe during the heel attaching operation. It will be appreciated that since heels of shoes of a given style vary in size it is desirable that the size of the heel-seat tab. be varied according to the size of the heel to be attached to the shoe.

It is an object of the present invention to provide a machine for quickly and efiectively reducing the heel-seat portions of soles of shoes of different sizes to form heel-seat tabs varying in size in accordance with the size of the sole of the shoe and, accordingly, the size of the heel to be attached to the shoe.

With the above object in view and in accordance with a feature of the present invention there is provided a heel-seat fitting machine having a matrix comprising a plurality of parts, means associated. with the matrix for positioning the heel-seat portion of a sole, means for measuring the sole widthwise and for effecting relative movement of said parts of the ma-, trix to vary the effective width of said matrix It is desirable that the heel-seat tab of the in accordance with the measured width of the sole, a knife, a presser member for conforming the heel-seat portion of the sole to the matrix, and mechanism for effecting relative movement of the knife and the matrix to reduce the heelseat portion of the sole, thereby forming on the sole a heel-seat tab.

In the illustrative machine the matrix is concave and comprises a pair of plates which are movable equal distances toward and away from each other for varying the effective width of the matrix in accordance with the width of the sole being operated upon. The sole is positioned lengthwise in the machine by moving the heelbreast receiving shoulder of the sole into engagement with front edges or faces of the plates of the matrix, the heel-seat portion of the sole underlyingsaid matrix. A one-revolution clutch is then tripped with the result that the matrix plates are moved toward each other by a spring until abutments on the plates engage theopposite lateral edges respectively of the sole, and a slide which carries the above-mentioned presser member and the knife is moved rearwardly past the lower face of the matrix, the presser member which comprises a plurality of individual spring pressed fingers serving progressively to force the heel-seat portion of the sole against the matrix, and the knife which has a straight cutting edge and trails the presser member reducing the heel-seat portion of, the

sole to a shape determined by the matrix. With the above-described arrangement the effective width of the matrix and accordingly the width of the resultant'tab formed by the machine varies in accordance with the width of the sole. At

the, end of the heel-seat reducing stroke the presser member is dropped away from the matrix to facilitate the removal of the U-shaped chip trimmed from theheel-seat portion of the sole.

In order to facilitate the subsequent application and permanent attachment of a flap split from the sole to the breast of a Louis heel attached to a shoe towhich the sole is attached, the illustrative heel-seat fitting machine comprises means for supporting ,a flap split from the sole of the shoe, and means comprising a rigid moldand a conformable presser member constructed and arranged to form at the lateral margins of the base portions of the flap crimps extending widthwise of the flap. 1

By the use'of the illustrative machine the heelseat portions of soles can be quickly and effectively reduced to produce heel-seat tabs of different sizes in accordance with the widths of the soles, said tabs in the finished shoes serving Fig. 1 is a perspective View; partlybroken away, of the illustrative machine;

In order effectivelyto support theplates'34 against' displacement during the tab-forming operation, and to insure against the formation of.

an open gap between rear portions of the faces I26 of the plates, through which gap therear. end of the heel-seat portion of the sole 22 otherwise might be forced during the trimming operation, there is provided the thrust block 35. which is secured by screws I33 to a support I34 secured to th mainframe. The beveled face I36 (Figs. 3, 4 and 6).of the-block 35 is constantly engaged by faces I31 of the matrix plates 34, the arrangement being such that the .face I36 is approximately continuous with the faces I26 of the plates 34 and serves as the rear end of the matrix when said plates arespaced from each other.

In order slightly to depress the opposite lateral margins of the sole 22 immediately ahead of its heel-breast line I38 (Figs. 9 and 10) so'that the shank reducing bevels I40 (Fig. 10) shall merge attractively with the forward beveled margins I42 of the heel-seat tab 24, there is provided a pair of lugs I44 (Figs. 1, 6 and '1) which override the sole and have upwardly and inwardly inclined sole engaging faces I46, respectively.

After the sole 22 has been positioned, as illustrated in Fig. 3, with its heel-breast receiving shoulder 30 in engagement with the front edges 32 of the plate, the clutch (not shown) is tripped causing the slide 44 to move rearwardly and the cam I30 to be moved out of engagement with the cam roll I32, thereby permitting the matrix plates 34 to close in on the sole until opposed abutments 38 of the plates 34 engage the opposite lateral edges of the sole. With such an arrangement it will be clear that the width of the matrix and, accordingly, the Width of the resultant heel-seat tab is varied in accordance with the width of the sole.

It is desirable that the heel-seat portion 20 of the sole shall be effectively conformed to the matrix during the tab-forming operation and, accordingly, there are provided, at opposite sides of the machine, cams I48 (Figs. 1, 2 and 4) shaped and arranged to be engaged by the trunnions 54 of the carrier 52 during the rearward movement of the slide 44, the arrangement being such that the presser fingers 12 during the rearward or operating stroke of the slide 44 forcethe sole with considerable pressure against the matrix. a r

In order to dispose of the U-shaped chip I4 (Fig. 4) trimmed from the heel-seat portion 20 of the sole 22, the presser member'40 is permitted to drop away from the knife, to the position illustrated in Fig. 5, as it arrives at the end of its operating stroke and is swung back to its raised position, shown in Fig. 2 during its retractive movement with the slide. In order to efiect the above-mentioned movement/of the presser member 40, the cams I48 are of suitable length to insure that when the heel-seat portion of the sole has been trimmed, the trunnions 54 will run off said cams, a screw I50 (Figs. 2 and 5) adjustably secured to a depending lug I52 formed integral with the lever 56 just prior to this time engaging a stop I54 to prevent the lever 56 from following up the roll 58 of the carrier 52. Downward pivotal movement of the carrier 52 with reference to the slide 44 is limited by the engagement of one of the trunnions 54 with a cam I56 which is so shaped that the carrier during its retractive movement is swung in a counterclockwise direction, as viewed in Figs. 2 and 5, the carrier at fromithecam I56'to its starting position, shown in Fig. '2, by the spring pressed lever 56.

, vTheslide 44 is operatively connected by a link I58 .(Fig.. 2) to .a lever I60 mounted upon a fulcrum pin I62. secured .to the. machine frame. A link I64 operatively connects the lever I62 and a cam I66 which is keyed to a drive shaft I68 and hasxa face I10 whichis engaged by a cam roll I12 carried by a rocker arm I14 fulcrumed upon a pin I16 secured to the machine frame.

The flap-molding block 36 is adjustably secured to the machine frame by screws I18 which pass through elongated recesses I of the. block and arethreaded into the machine frame. To facilitate the positioning of the molding block 36 and the retaining of the same in position, there is provided a thrust screw I82 which is threaded into the machine frame. The molding block 36 has a pair of laterally extending grooves I84 of V- shaped cross section arranged to co-operate with V-shaped projections I86 of the conformable pad 48 to form the crimps 28 in the heel-breast covering flap 26. It will be noted that the conformable pad 48 -comprises projections I88 for clamping the flap against the flat faces I90 (Fig. 2) of the molding block 36, the arrangement being such that the base portion of the flap is securely clamped between the projections I68 of the pad and the faces I90 of the molding block 36 before the base portion of the flap is stretched by the co-operative action of the associated grooves I84 of the block and the V-shaped projections I86 of the pad 48.

The pad 48 is bolted to a bracket I92 secured by screws I94 to the forward end of a lever I95 which is pivoted upon a fulcrum pin I96 secured to the main frame and is operatively connected to the rocker arm I14 by a link I98. The cam roll I1'2is constantly forced against the face I10 of the cam I66 by a spring 200 the forward and rear ends of which are secured to the lever I95 and to the machine frame, respectively.

' When the sole has been positioned in the machine as above described, the one-revolution clutch (not shown) is tripped, causing the knife 42 and the presser member 40 to co-operate with the matrix in reducing the heel-seat portion 20 of the sole 22 to form the heel-seat tab 24, and causing the'conformable pad 48 to force the flap against the molding block 36 to form the crimps 28 in the flap. The sole is removed from the machinewhile the operative parts of the same are returning to their idle positions, shown in Fig.
